varicose veins

varicose veins - is the common name of diseases in which the first and most striking feature will be the expansion of the network and the venous overflow its blood.Thinning of the blood vessels with varicose veins are very fragile and easily damaged. And as they at the time of damage to contain a large amount of stagnant blood, these vessels are damaged for a large volume of blood loss.

Classically, under the phrase "varicose veins" refers directly to the varicose veins of the lower extremities is.But the general concept of varicose veins is not only to this single diagnosis.There are also varicose esophageal veins and varicose veins in pregnant women, as well as varicose veins in the pelvis.The latter, incidentally, is found not only among women, but most of them have a strong half of mankind.

varicose veins

This subspecies of varicose veins most widespread and the most famous.It is, in turn, one of the three types of chronic venous insufficiency.This disease is charact

erized by the fact that the venous network of the lower limbs is losing its capacity for pumping blood from the lower parts of the upper and the advent of reverse pathological casts of small volumes of blood.These blood casts appear both in the vertical direction (in the previous sections and the underlying veins) and horizontally (casts made in the supporting network of veins).

This inadequacy of the venous system is a number of reasons.Among them, as always, can be identified as hereditary, and those causes that occurred after exposure to certain conditions.This working conditions, which are accompanied by high loads and prolonged standing, and exposure to diseases and hereditary defects.These reasons are all very different, but lead to the same effect - disrupted the normal course of blood through the vessels.There are veins of the lower extremities, visible "crimp" vascular insufficiency and venous valves work.Normally, these valves are similar in their work with the valves of the heart: they coordinate the blood flow and create his one-way movement.Here are just a vein valves are committed to transport blood from the lower parts of the upper.Furthermore, as all of the valve body, venous valves prevent the reverse flow of blood and pathological relaxations during heart.

When varicose veins valves may interfere with blood flow in the opposite direction.This is due to extensions of the vein.In turn, Vienna typically expands due to exposure to the elevated pressure in the bloodstream or through disturbance of the structure.Valves for varicose veins limbs as though "stretched" in different directions and the leaf can not be closed.Naturally directs blood enters the cylinder and under the influence of gravity is accumulated in the lower body, and in the case of varicose veins of the extremities - in certain areas of veins (generally near the valves insolvent).A large amount of blood gradually stretches the vein and it becomes thinner.In the same way can be activated bypass vein - collaterals, which are also overflowing with blood and become thinner.Most often it is deformed superficial varicose veins and collaterals, and are visible on the limbs of patients.

Such large veins and stagnation in them large amounts of blood will lead to a "crown" of complications and the appearance of varicose veins of the lower extremities - the appearance of ulcers on the skin of the legs, which are called "trophic".They appear due to the fact that in the area of ​​the lower leg pressure stagnant volumes of blood biggest.As a result, the smallest types of veins - venules are very permeable, and the liquid part of blood (plasma) goes into the space surrounding the venules.In this place will develop significant swelling and impaired nutrition of the surrounding tissues.The result is the very sores.

have varicose veins, there are two subtypes, according to the veins that are affected: primary and secondary varicose veins.If you have primary varicose veins are damaged only the superficial veins.Secondary varicose veins is accompanied by damage to the deep veins.Incidentally, it was the secondary option lesion is hereditary and occurs due to a congenital disorder valve structure.

The following stage of varicose veins:

- varicose superficial veins beneath the skin or in the skin, and is not accompanied by the presence of abnormal discharges of blood

-The common varicose veins, accompanied by the release of superficial veins or veins collaterals

- common varicose veins with abnormal discharge in the deep veins

varicose veins of the pelvis

Varicose Veinspelvis seen in both men and women.Women from varicose veins of the pelvis often suffer from ovarian vein, and men varicose veins affects the spermatic cord veins.It varicose veins in men is a very unpredictable disease.At advanced stages, it can lead to complete sterility of men.

As with all subtypes of the disease, have varicose veins of the pelvis contains the following reasons for its occurrence: the likely failure of venous valves, the violation of "pumping" of blood through the vessels and its stagnation and subsequent activation of the auxiliary network of vessels, to ensure that transport blood to bypass areasstagnation.

During certain problems ovarian vein or veins of the spermatic cord can not perform the necessary volume of pumped blood vessels in the next.As a result, certain parts of the blood is not transported, but stagnates and accumulates.Large amounts of blood putting pressure on the vessel wall veins and extend it.But veins have one secret - they are provided with an additional system of assistants --vein collaterals.These veins work as sidings in the human body.According to him stagnant blood rushes to your circle, avoiding the broken sections of the main veins.But these veins helpers even thinner than the main vein.So, after a while, and they are expanding.And showing signs of varicose veins of the pelvis.

As mentioned above, varicose veins of the pelvis is dangerous for both sexes due to the fact that may be the cause of their infertility.It is now believed that the varicose veins of the pelvis in women - a disease that has its background even during fetal development.To be precise, it is believed that the varicose veins of the pelvis occurs because of birth defects, the elasticity of the venous system.Rather, these defects are due to a congenital inability to produce certain types of collagen, which is a part of the wall of the vein and ensures its elasticity.

Therefore etiological causes of varicose veins of small pelvis in women there.But there are factors - conditions that are specified in the long-term and their impact can cause the appearance of varicose veins of the pelvic organs in women.Usually it is a job where a woman is forced to be a long time in an upright position, work in harsh physical conditions, a large number of pregnancies and births, gynecological diseases, as well as the possible effects of hormone replacement therapy and oral contraceptives.

Among the clinical manifestations of varicose veins of the pelvic organs in women are two subspecies: the first - a varicose vein of the vulva, perineum, and varicose veins of the uterus.The second option for varicose veins of small pelvis is a syndrome accompanied by venous congestion pelvis.

Men varicose veins seen the emergence of the so-called varicocele.It comes from the fact that in the testicular vein appears reversed blood.This reversal falls into acinar venous plexus eggs and rushes into the common iliac vein.

Most often reverse blood varicocele in men arises from the fact that the narrowed lumen of the renal vein or it increases the pressure that stimulates the emergence of this pathological course.Renal Vienna for varicose veins of the spermatic cord may narrow because of possible scarring processes or her wrong location behind the aorta.Also, reverse and varicose veins of the spermatic cord and may cause similar changes (stenosis or high blood pressure) in the common iliac vein.

varicose veins of the esophagus

varicose esophageal veins is slightly different reasons, compared with varicose veins.In addition, it never appears in itself and is in a complex with a disease such as portal hypertension.All this is due to the fact that a certain number of reasons in the portal vein (which comes from the liver), increased pressure gradient.

Esophageal veins according to their anatomy associated with the portal vein of the liver, and when the pressure rises there, it will not escape this fate and esophageal veins.Excessive pressure leads to a stretching of the venous wall.In contrast, arteries, veins, and even have the muscular wall, but it is far less developed than that of the arteries.So long to cope with the pressure they can not.After some time, the vein becomes thin, brittle.Therefore, at any point, they can break.And since these vessels are a lot of blood, like bleeding from the affected varicose veins are characterized by large volumes of blood loss and can lead to death.

also esophageal varices may appear in the situations of their compression.This can occur when the compression of the esophagus tumor.

The surest clinical symptom of varicose veins are bleeding.They can appear suddenly, without any preliminary degradation.This bleeding can also occur in the situations where the patient varicose veins may inadvertently natuzhitsya.In addition, weight lifting, too, can lead to tearing of esophageal varices and subsequent bleeding.High blood pressure, especially the jumps and extremely dangerous for patients with esophageal vessels, affected varicose veins.

In some patients, a kind of "beacon" forthcoming bleeding may be feeling that most will look like tickling.This "tickle" will be accompanied by a special sour-salty taste in the mouth.Then, these precursors will be replaced by copious vomiting blood.Most often it is scarlet, can sometimes be "color of coffee grounds."The color of blood at rupture of esophageal varices will depend on the veins of esophageal varices amazed.

If the blood loss with varicose veins of the esophagus has a large volume, it will go in a pair with weakness and dizziness.Also, patients may complain of a gradual "blackout" or loss of sensation in the limbs.Typically, patients with such bleeding is very restless, they feel a kind of "fear of death".

varicose veins of the esophagus can develop quite differently.It can develop as an extremely fast, lightning fast, and evolve over time.Interestingly, patients who have a risk of bleeding with a large and possibly lethal blood loss may feel some "harbingers" - for a few days before the bleeding, they note the appearance of the characteristic chest tightness.

and lightning-fast development and lasting manifestation of esophageal varices are dangerous to the life of patients.With lightning-fast form of esophageal varices, everything happens very fast and suddenly.Often, if the attack is not stopped bleeding, it will lead to death.Patients with long-term ("slow") forms of varicose veins often do not even know about his illness until the bleeding.

Varicose veins causes

Varicose veins - a category of diseases that are caused by many factors.Play a role here, and genetic aspects described above, and the impact of hormones (intake of certain substances in women, and pregnancy), excess body weight and the load at a higher growth of man.Also, it has been described causing varicose veins especially working and living conditions (inadequate constitution load exercise, the load on the legs and the transfer of such loads to which the body does not fit).

addition decided to allocate factors of development of varicose veins, which can be a precursor of the disease.That is, when such factors varicose veins can occur as and when properly supervised not develop even in the initial stage.Such factors predisposing called.

It predisposing factors are the above congenital vein valve insufficiency and failure of the vein wall.When these factors still in the process of development of the fetus fails, and since then not produce certain types of components of the vein wall and valves.Also there

producing factors of varicose veins: here include diseases and conditions that lead to the fact that the body and the pressure level rises vessels.By the disease include: COPD (chronic obstructive pulmonary disease, constipation, obesity).Refers to a state of pregnancy and heavy, static load.

Besides the causes of varicose veins need to understand the main reasons due to which there are certain clinical manifestations.About these reasons alone we have said, when describing a separate subspecies of varicose veins.

And besides predisposing factors and causing varicose veins, and there are also risk factors.These are factors that increase the possibility of the appearance of varicose veins: this includes conditions characterized by an imbalance between the hormones in the body.At the same time a risk factor and a factor that can trigger the disease are already described pregnancy, obesity and features of life and work.

Thus, it becomes clear that certain factors may as increase the chances of morbidity, and directly cause varicose veins.All depends only on the strength of their influence, combined with other factors and individual features of the organism.

main pathological link - a pathological blood reflux (reflux).Normally, the blood is on the channel from the upper to the lower divisions.That is, it counteracts the effects of gravity.This phenomenon provides the heart and the venous system, which "pump up" the blood from the bottom up.As described above, in the veins have valves that prevent blood flow in the body is not favorable direction - top to bottom.Normally, the valves are closed at the diastole of the heart and do not let the blood back.

varicose veins the valves do not close for cardiac diastole.This occurs because of different reasons: somewhere valves already defective at birth, but somewhere in the veins themselves are stretched by exposure to pressure (such as portal hypertension).Because of incorrect operation of the valves impaired blood flow, and there are casts.Casting is left in the veins of unnecessary amounts of blood, which stretched vessels.Gradually developing a second increased pressure in the veins.Therefore, the causal relationship of varicose veins is called "vicious circle": violation of the principles of hemodynamics in patients with varicose veins and cause and effect.
